You are assuming use-activation as a free action, and that is not always the case. There is a huge difference between use-activated (free action) and use-activated (standard action). Most of the misconceptions regarding this topic are because of a failure on many people's parts to take this into account.
When you step back and take a look at the options available, a use-activated (standard action) True Strike item isn't that bad at all. At high level, it's only really useful when you absolutely must make that one shot, like when you want to shoot down a chandolier with your bow, or carefuly fire an arrow with a note attached next to someone. It has many utilitarian purposes. At low level, say when you only have one or two attacks per round anyway, its great.
It certainly is not as nasty as a use-activated (standard action) Heal item.
Activating a use-activated magic item is either a standard action or not even an action and does not provoke attacks of opportunity, unless the use involves committing an action that provokes an attack of opportunity in itself. If the use of the item takes time before a magical effect occurs, then use activation is a standard action. If the item’s activation is subsumed in use and takes no extra time, use activation is usually not even an action.
Always good to quote the rules on this sort of topic.
But note that there is no price difference between a use-activated (standard action) item and a use-activated (no action) item.
Then again:
1. Item prices are only guidelines.
2. If this were a no-action use-activated type item, then it should probably be priced out by the bonus it grants, not by spell level (because it's not the same as the spell anymore).
As a use-activated item I think it would be VERY expensive.
(Bonus^2 times some multiplier) - insight is not listed in the DMG, but if we assume 2,500, then it would be:
(20^2)*2,500 or 1,000,000 gp. Whew!!
On the other hand, if it worked exactly like the spell, it would only be 6,000 gp. (3rd level caster, 1st level spell = 1 x 3 x 2,000 = 2,000). I suppose it could be done as cheap as 2,000 g.p. if powered only as a 1st level caster.
I don't know how the bow got priced out as costing only 1,500 for the True Strike part. Odd.
(It's worth noting that no errata on the bow has been published.)
